The BigBlue AL1800NP II Narrow Beam Dive Torch is the big brother to Bigblue's all-time best-seller, the AL1300NP. It has a bigger battery for increased light intensity and burn time. At 1800 lumens and a 10° beam angle, this light packs a powerful punch in a super small housing. The light comes with a battery, charger, and a dry bag for safekeeping. It includes a USB charger that is capable of charging 18650, 26650, or 32650 batteries.
